Minimum Tank Size: 500 litres (approximately 110 gallons) to accommodate its active swimming and territorial behaviour.
Lighting Requirements: Standard marine aquarium lighting is sufficient; no special lighting needs.
Water Flow: Moderate to strong water movement mimicking natural reef currents is recommended to promote health and activity.
